I know how to remove undesired elements from toolbar in general. However, what is the correct pattern in <activitypatternbinding> to remove "Previous/Next Annotation" and "Last Edit Location" from the toolbar?

Tracing keybinding as described at http://www.vogella.de/articles/EclipseCodeAccess/article.html#keybindings shows that IDs for commands are org.eclipse.ui.edit.text.gotoLastEditPosition, org.eclipse.ui.navigate.next, and org.eclipse.ui.navigate.previous, but adding pattern bindings for .*/org.eclipse.ui.edit.text.gotoLastEditPosition and .*/org.eclipse.ui.navigate.* doesn't work.

Strangely enough, .*/org.eclipse.ui.edit.text.* does, but I will quite likely need some commands for text editing later, so what's the best way to do this?
